Product Profile of Electro Pneumatic Double Flap Valve

Demech from the year 1969, manufactures various types of engineering products. Being a part of that demech offers different types of valves and are designed specifically for long life in handling abrasive materials while maintaining a positive seal against pressure and vacuum in dust collectors and other process equipment. Rotary air locks, by design, have leakage. When handling abrasive products, the air leakage increases rapidly due to the wiping, sweeping or scraping action that occurs during operation. Salient features of the valves are:

• They have a "perpendicular" seating action that minimizes wear. Consequently they can handle abrasive products, highly differential pressures and high temp. With an absolute minimum of leakage.

• The valves performs well as primary air locks under vessel in pneumatic conveying systems and also successfully operate as feeders to negative as well as positive pressure pneumatic conveying systems.

• Resilient seal design has literally no air leakage thus eliminating the "fluidization" that occurs above rotary air lock.
